Proximity Switches Position Sensing Products

Proximity Switches or Safety Interlock Switches are designed to control safety systems on automated processes. Proximity switches operate on the same principle as buoyancy level switches. A magnet is encapsulated in a sealed housing and attached to the controlled object (i.e. door, tray, cover, etc.). The switch assembly is also encapsulated within a sealed housing and mounted onto a stationary structure in line with the magnet. As the magnet moves toward or away from the switch, it changes state. Proximity switches are passive devices that do not require power to change states.
